FLUSHING-TANK.

SPECIFICATION forming part of Letters Patent No. 363,166, dated May 17, 1857.

Application tiled March 1S, 1887. Serial No. 231,429. (No model.)

and operation of the devices, and to provide aV simple adjustment of the parts whereby the amount of water admitted to the pan of the closet may be regulated as desired.

In the accompanying drawings, Figure l is a vertical section of my improved flushingtank. Fig. 2 is a corresponding view show- 'ing the float in its lowered position after it has caused the closing of the outletvalve. Fig. 3 is a plan View of the tank. Figil. is a perspective view of a detail drawn to an enlarged scale, and Fig. 5 is a view of a modification.

The tank A may be of any suitable construction, and it is shown in the drawings as of wood with a sheet-metal lining, and has the usual dischargeopening, B, to which is connected the pipe leading to the bowl or pan of the water-closet. This discharge-opening is provided with a concave or tapering valveseat, b, to which is fitted the valve D, having a suitable packing-ring, shown in the present instance as of round section. This valve D is hinged at d to the bottom of the tank, and carries an upright stem or rod, E. For convenience I prefer to make this upright stem of the valve the overflow-pipe; but this is not essential.

F is the inlet for the water-supply, provided with a valve, f, of any usual construction, and controlled by the hinged lever H, carrying the iioat H'.

There is pivoted to suitable projections on the tank a curved lever, J having a counterweight, j, at its lower end, and a finger or antifriction roller, t', in such a position that when the lever J is tilted by pulling on the cord, rod, or chain r this linger or anti -friction roller will strike the stem E of the hinged valve and throw it over from the position illustrated by full lines in Fig. 1 to that shown by dotted lines. The discharge-valve thus being raised from its seat, the water to iiush the pan of the closet below will flow out as long as the valveremains open.

The stem of the valve, when it is tilted over, comes into contact with and is supported by an arm, h, on the lever H of the iloat. As the iloat descends with the fall of water, the lever H will tilt the stem and its valve back toward the upright position until-by the time the iloat-lever reaches the position shown in Fig. 2, for instance-the valve D will fall backto its seat and close the outlet. The descent of the float H has at the same time opened the inlet-valvef, and the flushing-tank will iill up againin the usual way. Thus the one float-lever acts positively on both the inlet-valve and the hinged dischargevalve.

I prefer. to make the arm 7L on the lever H extensible by suitable means, so that the outlet-valve may be made to close sooner or later in the descending movement of the iioat, and the amount of water i'or ushing the pan of the closet in that way regulated, as desired.

The form of extensible arm which I prefer is illustrated more clearly in Fig. 4L, the portion k, carried bythe lever H, being in this instance bifurcated, and vhaving at its lower end a socket for the reception of the square or other-shaped stem 7c', which carries at its lower end the anti-friction roller p, to bear against the stem E of `the valve.

For convenience I prefer to bifurcate the float-lever H, so that the operative parts may be arranged in line with each other, the valvestem'being also guided by the bifurcated portion of the lever.

The lever J may be provided with stops s, acting in connection with a projection on the supporting-bracket to limit the movement of said lever in either direction.

Instead of bridging the distance between the iioat-lever and the stem of the valveby put` ting the projecting arm on the lever, the projection may be on the stem of the valve, in the form of a cam, h', as shown in the modification, Fig. 5. In this case the anti-friction roller p is mounted directly on the iioat-lever.

I claim as my invention l. The combination of the inletvalve of a lushingtank, and the hinged dischargevalve having anv upright stem, with the iioat-lever controlling the inletvalve, and constructed to strike the stein 'of the hinged discharge-valve to close it, substantially as described.

2. The combination of the inlet-valve of a flushingiank, and the hinged discharge-valve having an upright stem, with the float-lever controlling the inlet-valve, and having an arm to strike the stem of the hinged discharge-` valve to close it, substantially as set forth.

3. The combination of the inlet-valve of a flushing-tank and the hinged discharge-valve having a stem constituting an overlioW-pipe,

- v With the float-lever controlling the inlet-valve,

and constructed to strike the stem |of the dis- 15 charge-valve to close it.

4. The combination 0f the inlet-valve of a lushingtank, and hinged discharge-valve having a stem,with the iioat-lever having an extensible arm to strike the stein of the discharge- 2C valve, as vand for the purpose set forth.

In testimony whereof I have signed my name to thisspecilication in the presence of two subscribing witnesses.
